high-performance computing technologies, nanoporous systems with feedbacks, adsorption and desorption of gases modelling; Heaviside’s operational method; Laplace integral transform.

The paper deals with high-performance computing technologies of modeling and identification of adsorption in nanoporous systems with feedbacks for gas purification. Analytical solutions to the problem of non-isothermal adsorption and desorption are based on Heaviside’s operational method and Laplace integral transform, but the development of calculations is quite original. Experimental and modeling distributions of moisture and temperatures of gas at the inlet and outlet of the silica beds for each adsorption – desorption phase at different times are presented. The distribution of moisture within the beds for the full dehydration – regeneration cycle is determined.
